1. neat, immaculate. Clean,clear,pure refer to freedom from soiling, flaw, stain, or mixture. Clean refers especially to freedom from soiling: a clean shirt.Clear refers particularly to freedom from flaw or blemish: a clear pane of glass.Pure refers especially to freedom from mixture or stain: a pure metal; not diluted but pure and full strength.7. legible. 11. unsullied, chaste, virtuous. 19. unblemished, flawless. 34. entirely, thoroughly. 35. scour, scrub, sweep, brush, wipe, mop, dust, wash, rinse, lave, deterge, purify, clear; decontaminate. Clean,cleanse refer to removing dirt or impurities. To clean is the general word with no implication of method or means: to clean windows, a kitchen, streets.Cleanse is especially used of thorough cleaning by chemical or other technical process; figuratively it applies to moral or spiritual purification: to cleanse parts of machinery; to cleanse one's soul of guilt.

Old English clæne "free from dirt or filth; pure, chaste, innocent; open, in the open," of beasts, "ritually safe to eat," from West Germanic *klainoz "clear, pure" (cf. Old Saxon kleni "dainty, delicate," Old Frisian klene "small," Old High German kleini "delicate, fine, small," German klein "small;" English preserves the original Germanic sense), from PIE root *gel- "bright, gleaming" (cf. Greek glene "eyeball," Old Irish gel "bright").

"Largely replaced by clear, pure in the higher senses" [Weekley], but as a verb (mid-15c.) it has largely usurped what once belonged to cleanse. Meaning "whole, entire" is from c.1300 (clean sweep in the figurative sense is from 1821). Sense of "innocent" is from c.1300; that of "not lewd" is from 1867; that of "not carrying anything forbidden" is from 1938; that of "free of drug addiction" is from 1950s. To come clean "confess" is from 1919, American English.

clean in Technology

language A lazy higher-order purely functional language from the University of Nijmegen. Clean was originally a subset of Lean, designed to be an experimental intermediate language and used to study the graph rewriting model. To help focus on the essential implementation issues it deliberately lacked all syntactic sugar, even infix expressions or complex lists, As it was used more and more to construct all kinds of applications it was eventually turned into a general purpose functional programming language, first released in May 1995. The new language is strongly typed (Milner/Mycroft type system), provides modules and functional I/O (including a WIMP interface), and supports parallel processing and distributed processing on loosely coupled parallel architectures. Parallel execution was originally based on the PABC abstract machine. It is one of the fastest implementations of functional languages available, partly aided by programmer annotations to influence evaluation order. Although the two variants of Clean are rather different, the name Clean can be used to denote either of them. To distinguish, the old version can be referred to as Clean 0.8, and the new as Clean 1.0 or Concurrent Clean. The current release of Clean (1.0) includes a compiler, producing code for the ABCabstract machine, a code generator, compiling the ABC code into either object-code or assembly language (depending on the platform), I/O libraries, a development environment (not all platforms), and documentation. It is supported (or will soon be supported) under Mac OS, Linux, OS/2, Windows 95, SunOS, and Solaris. (http://cs.kun.nl/~clean/). E-mail: clean@cs.kun.nl. Mailing list: .

jargon

1. Used of hardware or software designs, implies "elegance in the small", that is, a design or implementation that may not hold any surprises but does things in a way that is reasonably intuitive and relatively easy to comprehend from the outside. The antonym is "grungy" or crufty. 2. To remove unneeded or undesired files in a effort to reduce clutter: "I'm cleaning up my account." "I cleaned up the garbage and now have 100 Meg free on that partition." [Jargon File] (1994-12-12)

The various forms of uncleanness according to the Mosaic law are enumerated in Lev. 11-15; Num. 19. The division of animals into clean and unclean was probably founded on the practice of sacrifice. It existed before the Flood (Gen. 7:2). The regulations regarding such animals are recorded in Lev. 11 and Deut. 14:1-21. The Hebrews were prohibited from using as food certain animal substances, such as (1) blood; (2) the fat covering the intestines, termed the caul; (3) the fat on the intestines, called the mesentery; (4) the fat of the kidneys; and (5) the fat tail of certain sheep (Ex. 29:13, 22; Lev. 3:4-9; 9:19; 17:10; 19:26). The chief design of these regulations seems to have been to establish a system of regimen which would distinguish the Jews from all other nations. Regarding the design and the abolition of these regulations the reader will find all the details in Lev. 20:24-26; Acts 10:9-16; 11:1-10; Heb. 9:9-14.
